How to Make a Simple Two Legged Walking Robot

One of the most difficult robot is two legged walking robot. Its balancing mechanism needs a complex circuit , lots of sensors, gyro, servos and mechanics. All the parts are controlled by microprocessors with complicated Firmware. But here we have made a very simple two legged walking robot for kids. To drive the legs we have used old CD player's door opening mechanism. Mechanical structures were made from iron wires.

    Please, I need a circuit valid for regulation also of rotation speed motor if wil be too fast.

    Otherwise can you suggest the metod to decrease rotation speed of the little motor DC? Thanks a lot .
